You would be better off running them off completely different circuits. |

What is the difference between the 4 and 5 pin relays ? My 79 Clubman Build Thread - http://www.turbominis.co.uk/forums/index.php?p=vt&tid=451008

careful, there are two types of 5 pin relay. There are 'changeover' relays which have both normally open (NO) and normally closed (NC) contacts, and then there is the 'double feed' relay wich is normally open, this has two common load pins and one battery pin. Both look the same, but differ. That said, forget these for now.

^^ Looks better simplify it a little. The switching circuit, take the live from the fused battery supply, and connect it to the relay coil( simple small loop at the relay). Then switch the ground for the coil. Less wiring  My 79 Clubman Build Thread - http://www.turbominis.co.uk/forums/index.php?p=vt&tid=451008

awe crap, its lamps, you want to take the switching live from the high beam live, but still switch the ground On 26th Oct, 2004 TurboDave16v said:

Would that mean the lamps would only work with the High Beam ON ?

On 21st May, 2012 Sprocket said: awe crap, its lamps, you want to take the switching live from the high beam live, but still switch the ground Yes, but I have just read the topic in its entirety, so take the live from where you want to, ideally something that will be off when the key is removed. I'm forgetting myself and i've wired up lamps many times. 55w bulbs going to be enough?

55w for the bulbs.... Not sure but it has to be better than what is on it currently My 79 Clubman Build Thread - http://www.turbominis.co.uk/forums/index.php?p=vt&tid=451008

thats exactly what I was thinking. This circuit will allow you to turn the lamps on whenever you want, just be sure not to leave them on, with a 30a drain the battery will be flat in no time.

With switching the ground, you only need to find a local ground at the switch and run one wire from each switch from inside the car, or what ever, and with taking the live from the fused side of the battery fed, if anything shorts it is all protected. Obviously install the fuse as close to the battery as you can. The loop wire only needs to jump from 30 to 85 with about a 6" long wire terminated in the same crimp.

Thanks Sprocket, so now the question is what cable to use ?  That polevot web site suggests current ratings for their wire. with 4 lamps at 55 watts, you should expect about 18a, so you'd want a 20 amp blade fuse for your first bank of four lamps with a something like a 25a wire daisy chained from the from the fuse through the relay to the lamps, and a 10a fuse and 12a wire for the other two lamps in similar fashion. I'd suggest something like 40a for the unprotected wire from the battery to the fuse for both relays irrespective (the shorter the better). The switching wires do not need to be huge 10a wire is more than adequate Also remember that the ground wires needs to be equally able to draw the current, so make sure you size those accordingly. Normlly with spot lights they ground through the body if they are metal, but I'd always add a ground wire to each lamp fixing or its own ground wire of at least the current draw of the bubs fitted. You could probibly get away with lower rated wires, but me personally I don't risk it. I always like to see a good margin between the wire rating and fuse rating, especially when using 130watt bulbs
